What is the US duty on EDTA trisodium from China?
The USITC extract imported on 25 September 2026 does not use the words EDTA trisodium, edetic trisodium, or trisodium salt EDTA. This page does not state a rate for those names.
The only description that uses the word trisodium is HTS 2835.29.30.00, Of trisodium. It stores 2.2 percent general and 11.5 percent other. That line is a phosphate. This page does not call it EDTA trisodium, and it does not copy those numbers onto the missing name. Ethylenediamine stores 5.8 percent and is not copied either. The anti-dumping file dated 16 May 2026 has no heading 2835 row and no heading 2921 row. This file does not store a Section 301 percent for a name it does not list. This page is the United States file only. It does not state an Australian duty or a ChAFTA percent.
